Roads and Transport Policing Command officers are re-issuing an appeal for witnesses and information after a motorcyclist died following a collision in Lewisham last year.

Officers are releasing CCTV images of three vehicles in a bid to trace the drivers, who they believe may have witnessed the incident or have information that could assist with their enquiries.

The incident happened on Friday, 12 September 2014 at around 10:20hrs on Loampit Vale (A20) at the junction with Jerrard Street, SE13. The motorcycle was travelling from the direction of the roundabout at Lewisham station, when it left the road and collided with a lamppost.

The London Ambulance Service attended, but the 22-year-old rider died later that day at hospital.

The victim was identified as Conrad Oscar Lewis-Pratt (30/11/1991) of Upper Brockley Road, SE4 and a post-mortem examination carried out on 18 September 2014 gave cause of death as multiple injuries.

The incident is being investigated by detectives from the Serious Collision Investigation Unit (SCIU) based at Catford and officers are appealing for the drivers of three vehicles in particular to come forward and help them with their enquiries.

Officers believe that a dark blue Volkswagen Passat (2010 model or later) and a silver Toyota Prius were in the area at the time of the collision. They are also keen to speak with the rider of a moped that was in the area and are appealing to the drivers of all three vehicles to contact police.

Detective Sergeant Richard Budd, from the SCIU, who is investigating the incident, said:

"This was a tragic incident, where a young man has lost his life on the road and his family have been left devastated by it.

"Despite extensive enquiries, we still don't know how or why this happened, but we think that the drivers of the two cars and the moped rider may have seen something that could help us to piece together the events of that morning.

"I must also stress that, at this stage, we are purely looking to speak to these drivers as potential witnesses, so I would urge anyone with information to contact us."

Anyone with information should call the SCIU at Catford on 0208 285 1574 or contact Crimestoppers anonymously on 0800 555 111.
